JOSEPH KINTZEL, OF HTJ'TCI-IISON, KANSAS.

THREAD-CUTTER.

Application filed September 29, 1914.

To all whom it may concern:

Be it known that I, JOSEPH KINTZEL, a citizen of the United States,residin at Hutchison, in the county of Reno and tate of Kansas, haveinvented certain new and useful Improvements in Thread-Cutters; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to new and useful improvements in thread cuttersand has for its object the provision of a device 'of the above characterwhich may be easily and quickly applied to an ordinary sewing machine.

Another object of my invention is the provision of a device of the abovecharacter which will have interchangeable blades so that one may besharpened while the other is in use, thereby keeping the device inconstant repair.

A still further object of my invention is the provision of such a devicewhich will be cheap in construction, simple in operation and effectivein use.

With the above and other objects in view I now proceed to describe myinvention in the following specification and accompanying drawings, inwhich,

Figure 1 is a detail perspective view of my improved thread cuttingattachment, Fig. 2 is a longitudinal sectional view taken through thecenter of my improved thread cutter, and Fig. 8 is a detail perspectiveview of one of the blades which may be used in connection with myimproved thread cutter.

Referring to the drawings by characters of reference 5 indicates thebody portion of my improved thread cutter having formed in the endthereof the slot 6. This slot 6 preferably extends throughout the entirewidth of the body portion and is adapted to receive a blade. The end ofthe body portion opposite the slotted end is preferably extended andcurved upwardly as clearly illustrated in the drawings at 7 and tapersgradually to the end 8. A suitable transversely extending aperture 9 isformed in the bottom face of the enlarged end of the thread cutter andcommunicates with the slot 6, previously described. EX-

Speeification of Letters Patent.

Serial No. 864,132.

tending substantially in a line with the aperture 9 and throughout theentire thickness of the body portion I also provide the apertures 10which are adapted to receive set screws by means of which the device isattached to a sewing machine of any suitable type.

The blades indicated by the numerals 11 and 12, respectively, areprovided with the facial recesses 13 which are adapted to register withthe aperture 9 when the device is in use. These blades 11 and 12 areprovided with the sharpened edges 14-, against which the thread isadapted to be passed when it is desired to cut the same. A suitable setscrew 15 is adapted to be passed through the apertures 9 and 13 andremovably secure the blades in place.

It will be clearly seen from the foregoing that by means of theapertures 10 through which suitable set screws are adapted to pass thebody portion of my improved thread cutter is adapted to be secured to asewing machine of any preferred type and it will be obvious that bypressing the thread against the sharpened edge of either of the abovedescribed blades, said thread will be cut at the desired point withoutnecessitating the use of a separate instrument to perform this function.Owing to the interchangeability of the blades it will be obvious that ablade of any suitable construction may be used in connection with myimproved thread cutter and should any blade become chilled from use itmay be re moved and another substituted therefor, without causing anyinconvenience to the operator.

While in the foregoing I have shown and described the preferred form ofmy invention, I wish it to be understood that I may change the specificarrangement of parts without in any way departing from the spirit andscope of my invention.

WVhat is claimed is A. device of the class described comprising asubstantially rectangular body, one end of said body provided with acentral slot forming arms, one of said arms provided with ascrew-threaded aperture, the opposite end of said body being tapered andcurved upwardly and having spaced openings therein to receive fasteningmembers for Securing the device in position, a blade provided on oneface With a recess alining with In testimony whereof I affix mysignature the opening in the arm of the body, and a in presence of twoWitnesses. set screW fitted in said screw-threaded aper- JOSEPH KINTZEL.ture of the arm and engaging the recess in Witnesses:
